Here's thing about MS. The success of the 360 has depended LARGELY on the US market. Throughout the rest of the world, their console has not done nearly as well. Going into this coming generation, MS is not going to enjoy the built in advantages over Sony that they had last generation such as the 1 year head start, pricing advantage, ease of development advantage, etc. I've said all along that all Sony has to do is reach 50% market share in the U.S. and they will lead comfortably in global market share. Not saying the Xbox One won't be a viable platform but they shouldn't expect the level of US dominance they enjoyed with the 360.
